These are the best tracts out there. I visit Kenya, Africa every year for missions work & we take these tracts with us. They have an English side & a Swahili side. I use the English only tracts here in the US. I really like to hand them out to homeless people inside of a care package. They make sharing the Gospel so simple. The scriptures are wonderful & the tract makes it easy for anyone to understand why they're a sinner & why they need Jesus. The salvation prayer at the end makes it easy for anyone to trust Jesus. I highly recommend these tracts.
The only negative thing I can say about these tracts is that they take a looooooooong time to receive. I've been waiting for over 2 months to get my new ones, as they've been back ordered for a very long time. In my opinion, that speaks volumes about how great these are. If you plan on using these often I would suggest you order plenty or order long before you run out of the ones you already have.
Before I became a Christian I used to pick up tracts like these and loved to read them :) Now I carry them with me ALL the time and leave them everywhere and hand them out when I share the Good News with someone :)
